I took another sip of my beer and winced. The liquid had gone flat and lukewarm - a crime against both brewing and my taste buds. The dim glow of my laptop screen cast strange shadows across my cramped living room, the torrent client's progress bar frozen at a stubborn zero percent.

  "Come on, you digital dinosaur." I tapped the screen with my finger, as if that would somehow speed up the non-existent download of "Abbott and Costello Meet Frankenstein." The loading circle just kept spinning, mocking my attempts at a nostalgic movie night.

  "Nobody seeds the classics anymore." I slumped back into my worn canvas armchair, the familiar creak matching my mood. "What are they teaching these kids? Funny memes, YouTube clips and cat videos, while pure comedy gold gathers digital dust."

  The laptop's cooling fan whirred to life, probably struggling with the dozen browser tabs I had open. Each one displayed a different torrent site, all equally useless in my quest. The apartment felt too quiet, too still - the kind of silence that made you notice every small sound. The hum of the refrigerator. The distant traffic. The occasional ping from my magical firewall detecting another routine scan of the city's digital infrastructure.

  I set the offensive beer aside and rubbed my eyes. The clock in the corner of the screen showed 11:23 PM - too late to be this frustrated over a failed movie download, too early to give up and go to bed. My new augmented reality glasses sat folded on the desk, their subtle magical indicators pulsing with a soft blue light that meant everything was normal. Battery almost dead even though I charged them three times already today. No alerts, no emergencies, no mysterious magical signatures in the network.

  "Maybe I should've stuck to DVDs or cable," I muttered, clicking refresh for the hundredth time. "But noooo, I had to go hunting for the original uncut version. Because apparently, I hate myself and love spending Friday nights fighting with peer-to-peer networks."

  The progress bar jumped to 0.01% and then immediately dropped back to zero.

  "Oh, that's just cruel." I leaned forward, squinting at the screen. "You're worse than that time I tried to trace that cursed email chain through the magical dark web. At least that had the decency to try to hex me instead of this slow torture."

  A sudden warmth against my thigh made me jump, nearly knocking over the forgotten beer. The ECHO or Energy Channeling & Historical Observer device in my pocket was pulsing - not the gentle rhythm of standby mode, but an urgent, almost frantic pattern that sent tingles through my leg.

  "What's got you so excited?" I pulled out small brass box that closely resembled a vintage USB drive, with retractable USB connector and small crystal viewfinder glued on one side. The runic engravings caught the laptop's glow as I placed it carefully on my desk, next to my half-finished case notes and a stack of take-out menus.

  Something wasn't adding up. The device needed a direct line of sight to the archives to function - that's what Goran had drilled into my head during the brief training session. "Never use it without proper line of sight," he'd warned, "Unless you want to create another time loop in the card catalog."

  The crystal viewfinder pulsed with colors I'd never seen during our testing sessions. Instead of the usual soft blue or cautionary amber, it swirled with deep purples and flashes of silver that reminded me of lightning trapped in a bottle. The status LED shifted through its spectrum faster than my eyes could track.

  "This can't be right." I leaned closer, careful not to touch the device. The traces in the viewfinder formed patterns that looked almost like... code? Binary strings twisted and morphed into ancient Slavic runes, then back again, as if the device was trying to translate something it couldn't quite understand.

  My augmented reality glasses started beeping - soft warning tones that grew more insistent by the second. When I slipped them on, the magical overlay showed energy readings that made no sense. According to the display, the ECHO was receiving data from somewhere, but the source couldn't be identified as it was obviously not being in my line of site let alone anywhere in my apartment.

  "Either you're malfunctioning," I told the device, "or something very interesting is happening in Belgrade's digital underbelly tonight." The ECHO's only response was another flash of purple light, stronger than before.

  I rubbed my temples, remembering the day Goran had handed me the ECHO. "This isn't a toy, Aleksandar," he'd said, his usually warm voice carrying an edge of concern. "It's bleeding-edge tech, barely tested. The quantum buffer alone could tear a hole in..." He'd trailed off, probably realizing that explaining magical quantum mechanics to an ex-cop would be like teaching calculus to a cat.

  The memory brought a wry smile to my face. Two years ago, I'd been chasing petty thieves and junkies. Now here I was, in private sector, part of the Team for Operational Magical Analysis - TOMA, dealing with magical malware and digital curses. Life had a funny way of throwing curveballs - or in my case mystic magical memes.

  "You'll need this more than most," Goran had added, his blue eyes intense. "You see patterns others miss. That's why we recruited you." He hadn't mentioned that those "patterns" would include tracking dark web covens and decrypting spells hidden in spam emails.

  My fingers traced the brass casing of the ECHO. The Order of Perun had come a long way from its ancient roots as warrior-priests. On paper, we were GG Security Solutions - just another cybersecurity firm in Belgrade's growing tech sector. Our office even had those motivational posters about "digital safety" and "protecting your data" that every IT company seemed required to display.

  But behind the corporate facade, we fought a different kind of war. While our regular employees patched firewalls and updated antivirus software, the magical division tracked hackers who wielded keyboards and curses with equal skill. The digital age had given ancient evils new weapons, and someone had to stand guard at the intersection of magic and technology.

  The ECHO pulsed again, stronger this time. Whatever it was picking up, it wasn't normal network traffic. Normal didn't make prototype magical devices act like overexcited Geiger counters. Normal didn't send purple light dancing across my ceiling in patterns that reminded me of psychedelic 70's party.

  A sharp ping cut through my musings, this one from the company's secure messaging system. The notification blinked urgent red - never a good sign at this hour.

  My eyes scanned the message, then read it again, slower this time. Archive systems across Belgrade were going dark. Not just one or two, but dozens simultaneously. The National Library. The Historical Archives of Belgrade. Even our own digital storage facilities.

  "This can't be a coincidence." I mumbled, sliding my mouse pointer over the screen as I pulled up system status reports. The ECHO's pulsing suddenly made more sense - it wasn't malfunctioning, it was warning me.

  I pulled up the security feeds, my fingers, not more than two at the time as I never learned to type like everyone else, stabbed at the keyboard. Multiple windows populated my screen, each showing a different server room across Belgrade. The National Library's massive data center dominated the central display - rows of blinking servers stretching into the artificial twilight of emergency lighting.

  Through my AR glasses, the feeds took on an entirely new dimension. Ethereal patterns rippled across the screens like heat waves over hot asphalt. Most people would've missed them completely, or written them off as video artifacts. But I'd seen something similar during that nasty business with the cursed blockchain last summer.

  "There you are, you sneaky bastards." I leaned closer, adjusting the glasses' sensitivity. The magical residue flows weren't random - they moved with purpose, following the data cables between servers. The pattern reminded me of the viral spells Estonian hackers had used in their previous attacks, but this was different. More sophisticated. More controlled.

  The feed from the Historical Archives showed the same phenomenon, but with an interesting twist. The magical energy seemed to concentrate around the older storage systems - the ones still holding digitized records from the pre-war period. Whatever this attack was, it had a thing for history.

  "Classic misdirection," I grunted, recognizing a familiar strategy. "Hit the public archives to draw attention while..." My eyes darted to the feed from our own facilities. Sure enough, the same ethereal dance was playing out there, but so subtle I almost missed it. Whoever designed this attack knew exactly what they were doing - and they knew we'd be watching.

  The ECHO device lighted up in sync with the energy patterns now, its crystal viewfinder reflecting the same purple hues I saw through the AR glasses. The correlation sent a chill down my spine. This wasn't just some random magical hack - this was coordinated, planned, and far too precise to be a coincidence.

  I pulled up the security logs. The entries were, mildly put, a huge mess - timestamps jumped randomly, authentication records disappeared mid-line, and access protocols showed impossible user combinations.

  "That's not how computers work," I scoffed, quickly capturing screenshots. The corruption followed a pattern - every thirteenth entry showed traces of magical manipulation. Ancient Slavic numerology meeting modern technology. Cute.

  The messaging board lit up like a Christmas tree. The Museum of Science and Technology's database went dark. Then the University Library. The Serbian Film Archive. Each notification drove home just how massive this attack was.

  My AR glasses highlighted magical residue in the corrupted data - a signature I'd never seen before. Purple-tinged code fragments that somehow reminded me of old church manuscripts. I recorded everything, knowing Goran would want every detail.

  My phone buzzed, Ljiljana's contact photo, smiling granny hugging a shocked black cat, lighting up the screen just as I reached for it. The timing was uncanny - I hadn't even unlocked it to call for backup.

  "Hello? Aleksandar? Is this thing working?" Ljiljana's voice came through muffled, as if she was speaking into the wrong end of the phone. "These modern contraptions, I swear they get more complicated every day. Can you hear me? Where do I talk into?"

  "Other end, Ljiljana." I couldn't help but smile despite the situation. "The speaker goes by your ear."

  "It looks totally the same on both ends… Ah! There we go." Her voice cleared up. "Listen, something's very wrong. My protection crystals started humming ten minutes ago - all of them at once. Haven't seen anything like it since that mess with the cursed crypto-thingy-something."

  I glanced at the ECHO, still pulsing its eerie purple light. "Yeah, I'm seeing it too. Every archive in Belgrade is going dark. The ECHO picked up some strange patterns-"

  "That infernal device!" Ljiljana cut me off. "I told Goran it's playing with forces we barely understand. By the way, my coffee this morning had some strange dark spots—looked just like broken chains. I should've guessed it meant trouble with those digital chains."

  "The patterns match what you're sensing?" I pulled up another system status window. "Because whatever this is, it's spreading fast."

  The chaos stopped as suddenly as it had started. One moment my screens were filled with cascading errors and energy flow, the next - nothing. The feeds showed normal server operations, status lights blinking their usual steady green.

  "What the..." I refreshed the monitoring dashboard. Everything reported normal functionality. The ECHO's purple glow faded to its standard soft blue standby state, as if nothing unusual had happened.

  "Ljiljana, are you seeing this? Everything's just... stopped."

  "My crystals went quiet too." Her voice seemed on edge. "Just like that - as if someone flipped a switch. I don't like it, Aleksandar. Magic doesn't just stop by itself like it's battery died."

  I pulled up the system logs again. "This is weird. There's no trace of the attack. No error messages, no access violations, nothing." I glanced at my second monitor where the screenshots I'd taken still displayed the corruption patterns. "Good thing I grabbed these. Without them, we'd have no proof this even happened."

  "Those modern devices of yours finally proved useful for something," Ljiljana chuckled, though the tension remained in her voice. "I'll call Goran right away. He needs to know about this - especially that purple energy you mentioned. Never heard of anything like it in all my years."

  "Yeah, this feels too professional." I saved the screenshots to multiple secure locations. "We don't often have magical attacks this sophisticated and advanced."

  "Keep monitoring tonight, just in case." Ljiljana's voice took on that grandmother-knows-best tone she used when worried. "I'll brief Goran on what we've seen. Meet at the office first thing tomorrow?"

  "I'll be there early. We need to compare notes with the team before this trail gets any colder." I rubbed my tired eyes. "Seven AM?"

  "Make it six-thirty. And Aleksandar? Get some sleep and eat something. This job makes you thinner every day."

  The call ended, leaving me alone with my humming laptop and the now-quiet ECHO. My abandoned beer sat forgotten on the desk, a ring of condensation marking its place like a tiny crop circle.

  "So much for Abbott and Costello," I huffed, settling in for a long night of watching digital shadows.
